| 摘 要： | 采用电絮凝-超滤（electrocoagulation-ultrafiltration，EC-UF）组合技术对含铜废水中的铜离子进行了处理实验研究。讨论了电流密度、初始pH、初始铜浓度和初始电导率等因素对铜的去除效果和膜污染的影响，并分析了这些影响因素对EC-UF组合技术效率的作用机制。结果表明，在电流密度J=50 A·m-2、初始铜浓度C（Cu2+）≤40 mg·L-1、初始pH=4~8、初始电导率σ=2 mS·cm-1、电解时间20 min的条件下，废水中铜的去除率达到99.6%并有效的减缓了膜污染。本研究为EC-UF组合技术除铜的实践应用提供了科学依据。

| Abstract: | This study investigated the performance of copper removal from synthetic model wastewater by hybrid electrocoagulation and ultrafiltration processes (EC-UF).The effects of current density, initial pH, initial copper concentration, solution conductivity, and other factors on the removal of copper and membrane-fouling were studied, and the influence mechanism of these factors on EC-UF efficiency was analyzed.The copper removal rate was found to reach 99.6%, and membrane-fouling was effectively alleviated at a current density of 50 A·m-2, initial C(Cu2+) ≤ 40 mg·L-1, initial pH of 4 to 8, solution conductivity of 2 mS·cm-1, and electrolysis time of 20 min.These results provide a scientific basis for further research on EC-UF removal of copper ions. |
